生成證書

#1.生成CA證書
# 生成CA證書,執(zhí)行命令后,系統(tǒng)還會提示你輸入密碼,可以直接留空
cd /usr/share/elasticsearch/bin
./elasticsearch-certutil ca#會在/usr/share/elasticsearch/下生成一個elastic-stack-ca.p12文件
ls -l /usr/share/elasticsearch/
-rw-------. 1 elastic elastic 2527 May 21 14:29 elastic-stack-ca.p12#2.根據(jù)elastic-stack-ca.p12文件 生成elastic-certificates.p12
# 生成證書和私鑰,系統(tǒng)還會提示你輸入密碼，你可以輸入證書和密鑰的密碼，也可以留空
cd /usr/share/elasticsearch/
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12

把生成的證書放到 /etc/elasticsearch/目錄下，并授權(quán)

不加認(rèn)證，啟動集群模式

egrep -v “#|^$” /etc/elasticsearch/elasticsearch.yml

node.name: es1
path.data: /app/es/data
path.logs: /app/es/log

#xpack.security.transport.ssl.truststore.path: elastic-stack-ca.p12
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

啟動集群，查看狀態(tài)

curl -XGET  "http://127.0.0.1:9200/_cat/nodes"

添加認(rèn)證和證書，重啟集群

egrep -v “#|^$” /etc/elasticsearch/elasticsearch.yml

cluster.name: es
node.name: es1
path.data: /app/es/data
path.logs: /app/es/log

設(shè)置口令

./bin/elasticsearch-setup-passwords interactive

查看集群信息

curl -XGET -u elastic:123456 "http://127.0.0.1:9200/_cat/nodes"
